New research sheds light on the earliest days of the earth's formation and potentially calls into question some earlier assumptions in planetary science about the early years of rocky planets.

The Earth is four and a half billion years old, so why they started appearing then is unknown, as is the mechanism to make ...

Researchers have made a new discovery that changes our understanding of Earth's early geological history, challenging beliefs about how our continents formed and when plate tectonics began. A study ...

In a new study, astronomers report novel evidence regarding the limits of planet formation, finding that after a certain point, planets larger than Earth have difficulty forming near low-metallicity ...

Planetary scientists have long debated where the material that formed Earth comes from. Despite its location in the inner solar system, they consider it likely that 6–40% of this material must have ...

Old crystals found in Western Australia are drawing fresh attention from geologists studying the formation of Earth. These minerals, called zircons, have been dated to be older than four billion years ...

A new global study is offering a clearer view of how some of the world’s most valuable mineral deposits form, tracing their ...

Modern continental rocks carry chemical signatures from the very start of our planet's history, challenging current theories about plate tectonics. Researchers have made a new discovery that changes ...
